Measurement-based quantum computing (MBQC) is a leading model for quantum computation. In contrast to the circuit model, it exploits highly entangled universal resource state, on which computations are driven by local measurements. This allows for blind quantum computing as a secure technique for cloud-based quantum computing and facilitates stabilizer error correction codes. MBQC has been implemented in a variety of platforms, including photonic and trapped-ion quantum hardware in recent years. However, the vast majority of work is restricted to qubit-based cluster states. Employing multi-level information carriers instead has the potential to elevate MBQC to a new level of potential, since qudit systems feature a more extensive gate set, enhanced efficiency in encoding and computation as well as more complex entanglement structures. In consequence, resource states that extend beyond the well-known qubit cluster state, can be harnessed for MBQC. The presentation will report on the exploration of Qudit-MBQC with a state-of-the-art trapped-ion quantum processor.
